Dear Colleagues,

I hope this message finds you well. I am working on a research project involving the development of a Mixed-Integer Linear Programming (MILP) model for optimizing quality-based supply chain management, particularly focusing on managing the deterioration of perishable food items.

I have written the preliminary LINGO code for this model, but unfortunately, it is not functioning as expected. The variable values (solutions) are incorrect or not converging as anticipated, and despite my best efforts, I am unable to resolve the issue.

I am genuinely seeking help from someone with expertise in MILP modeling and supply chain optimization who can assist me in debugging and improving the code. Your contribution would be highly valuable, and in recognition of your efforts, I would be more than happy to offer co-authorship on the paper once the work is successfully completed.

If you are willing to help or guide me through the corrections, please do not hesitate to reach out. I would greatly appreciate any advice or support.

Looking forward to your response.

Best regards, Ashish Kumar
